The invention discloses a self-centering floating clamp. A bottom plate, an installing plate and a floating part which are sequentially arranged in the Z axis direction are included; first supportingrods are symmetrically arranged on the bottom plate in the X axis direction; second supporting rods are symmetrically arranged on the installing plate in the Y axis direction; the first supporting rods and the second supporting rods both extend in the Z axis direction; the free ends of the first supporting rods are provided with first connection parts rotationally connected with the floating part;the free ends of the second supporting rods are provided with second connection parts rotationally connected with the floating part; and the first connection parts and the floating part are in clearance fit with each other, and the second connection parts and the floating part are in clearance fit with each other, so that the floating part moves in the directions of the X axis and the Y axis relative to the bottom plate, or swings in a space formed by the X axis and the Y axis relative to the bottom plate. The self-centering floating clamp at least has the following beneficial effects that floating of the installing plate in the plane and swinging of the installing plate in the space can be achieved, the precision of centering is improved, and the structure is optimized.

The invention relates to a double-eccentric sanding mechanism of a sanding machine, comprising a motor (1), a fan blade (2), a flange (5) and a working bottom plate (10) with a grinding piece at the bottom surface, wherein the fan blade (2) is sheathed on a main shaft of the motor (1); the flange (5) is fixedly connected with the working bottom plate (10); the double-eccentric sanding mechanism further comprises an eccentric block (3) and a bearing (6); the eccentric block (3) is sheathed on the fan blade (2); the matching position of the fan blade (2) and the eccentric block (3) is provided with a stopping block (2-1) for stopping the rotation of the eccentric block (3); the flange (5) is in interference fit with the excircle of the bearing (6); the incircle of the bearing (6) is sheathed on the eccentric block (3) and is fixedly connected with the eccentric block (3); and the fan blade (2) is provided with an eccentric column (2-2) which is provided with a shaft hole matched with the main shaft of the motor (1). In the double-eccentric sanding mechanism, the swinging amplitude of the working bottom plate can be adjusted according to the requirements, so that the sanding efficiency of the sanding machine is greatly improved.

The invention relates to a bodybuilding bicycle which comprises a bicycle frame, a driving wheel and driven wheels. The driving wheel and the driven wheels are installed on the bicycle frame. The driven wheels are located at the front portion of the driving wheel. Two independent chain wheels are arranged on a middle shaft of the bicycle frame and symmetrically arranged on the left side and the right side of the bicycle frame. Flywheels corresponding to the chain wheels are installed at the two ends of a hub of the driving wheel. Each chain wheel and the corresponding flywheel are connected through a closed chain. The two chain wheels are further provided with pedals for controlling the chain wheels to rotate. The bodybuilding bicycle has the beneficial effects that two chain wheel systems working independently are arranged so that a person can ride the bicycle in a walking manner, and the person can build the body conveniently; through design of the bicycle in the technical scheme, the bicycle is more user-friendly and more flexible in use; and universal parts of an existing bicycle are used for design, so that the manufacturing cost and the maintenance cost are low, and the bicycle can be used conveniently by people.

The invention relates to the technical field of feed processing equipment, and discloses a livestock feed screening device. The screening gear is installed in the middle position, the connecting frame is fixedly installed on the front and rear sides of the screening shaft, the screening plate close to the inner bottom side of the screening box is installed at the bottom of the connecting frame, and the limit plate is installed on the upper side of the screening box through the limit frame The limit plate is installed with a power mechanism that drives the reciprocating rotation of the screening shaft. The power mechanism includes a lift assembly and a drive assembly that drives the movement of the lift assembly. An adjustment assembly for adjusting the reciprocating depth of the lift assembly is also installed between the drive assembly and the lift assembly. The invention not only realizes the sieving of the feed, but also ensures the grinding of the feed with larger particles, and avoids the effective waste of the feed. the screening efficiency.

The invention relates to building waterproof construction, and relates to a waterproof roll paving device. The waterproof roll paving device includes a substrate; a discharging device is arranged on the lower side of the base plate; the discharging device comprises two first fixing plates arranged in parallel; the first fixing plates are fixed to the lower side of the base plate; one of the firstfixing plates is fixedly connected with a fixed inserting roller, and the other first fixing plate is provided with a sliding hole; a sliding column is slidably connected into the sliding hole; one end of the sliding column is fixedly connected with a movable inserting roller; and the fixed inserting roller and the movable inserting roller are coaxial and are oppositely arranged. A spraying angleof a spraying gun is controlled through a swinging device; the spraying gun is driven to horizontally move through movement of a sliding block; the waterproof roll is uniformly heated, and the bondingperformance of the waterproof roll can be effectively improved; the device can adjust the swinging angle of the spraying gun as well as the swinging amplitude of the spraying gun, and is suitable forbeing used for waterproof roll paving operation.
