Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as Figure 1-5 As shown: the gear reducer 1 is composed of a driving gear 1-1 installed in the gear box, two idler gears 1-2 which are installed in the gear box and mesh with the driving gear, are located in the installation gear box and are connected to the gear box. The split gear 1-3 is composed of two idler gears meshing; the two ends of the split gear have bosses 1-5 in a C-shaped structure, and the outer cylindrical surfaces of the two bosses 1-5 are the same as the axis of the split gear 1-3. Shaft, and the diameter of the outer cylindrical surface of the two bosses 1-5 is smaller than the diameter of the open gear 1-3. The gear box is formed by combining and fixing the box body 1-4 and the box cover 1-8, and the corresponding positions of the box body 1-4 and the box cover 1-8 are provided with positioning round holes 1-7 a...

Abstract

The invention discloses a steel bar splicing sleeve screwing pipe wrench, and aims to provide a steel bar splicing tool capable of realizing the connection of two sections of steel bar mesh cages. Thesteel bar splicing sleeve screwing pipe wrench comprises a power source, a gear reducer and a rotary chuck; the gear reducer (1) is composed of a driving gear (1-1), two idle gears (1-2) and an opening gear (1-3) which are installed in a gear box, a positioning circular hole (1-7) with a notch (1-6) is formed in the gear box, and the opening gear (1-3) is correspondingly positioned in the two circular holes (1-7) through two bosses (1-5) on the opening gear (1-3); the rotary chuck (5) is composed of a C-shaped chuck body (5-5) provided with a wedge-shaped groove (5-3) and a pin roller (5-2) which is located in the wedge-shaped groove (5-3) and installed on a retainer, the retainer is composed of C-shaped plates (5-1) fixed on the two end faces of the chuck body (5-5), a mandrel of the pinroller (5-2) extends into a corresponding guide groove (5-4), and the rotary chuck (5) is fixed on the opening gear (1-3); and the power source (3) is connected with the driving gear (1-1).

Description

technical field [0001] The invention relates to a pipe wrench, in particular to a steel bar extension sleeve twisting pipe wrench, which belongs to a steel bar extension tool. Background technique [0002] The butt connection of two sections of steel bars using the connecting sleeve is a new process of steel bar connection following the binding process and welding process. It has many advantages such as high joint strength, fast connection speed, and steel saving, and is widely used in the construction industry. At present, manual tools such as wrench or ordinary pipe wrench are usually used to screw the connecting sleeve or reinforcing bar, so that two sections of reinforcing bars are screwed into the connecting sleeve to realize docking. Although this method is relatively simple, it is labor-intensive and inefficient. [0003] For this reason, "CN208960871U" and "CN210189680U" disclose two kinds of portable threaded steel fast connecting devices with different structures ...
