Embodiment 1

[0018] Example 1: as figure 1 As shown in the figure, the anti-reverse-installation composite tool holder for the lawn mowing vehicle provided in the present embodiment 1 includes a blade 4 and a tool holder 5. The tool holder 5 includes a base and a mounting seat perpendicular to the base. The base is connected to the blade. 4. Two bosses are arranged on the abutting surface; the blade 4 is fixedly arranged under the knife seat 5, and two grooves corresponding to the bosses are provided on the part that is fitted with the base of the knife seat 5.

[0019] The mounting seat on the knife seat 5 is cylindrical, and the two bosses are evenly distributed in the circumferential direction with the center of the butting part of the base and the mounting seat as the center, and are symmetrical with the center of the butting part of the base and the mounting seat. The sections of the bosses are all arcuates with an area larger than a semicircle.

[0020] The inner wall of the mountin...

Embodiment 2

[0022] Embodiment 2: The structure is basically the same as that of Embodiment 1, and the similarities are not repeated, but the differences are:

[0023] The blade holder 5 is provided with two semicircular bosses which are axially symmetric with the diameter of the circular cross-section of the butting portion of the base and the mounting base, and the blade 4 is correspondingly provided with two semicircular grooves.

Embodiment 3

[0024] Embodiment 3: The structure is basically the same as that of Embodiment 1, and the similarities are not repeated, but the differences are:

[0025] The blade seat 5 is provided with four triangular bosses that are symmetrical with the center of the bottom of the mounting seat and evenly distributed in the circumferential direction, and the blade 4 is correspondingly provided with four triangular grooves.

[0026] Taking Embodiment 1 as an example, the working principle of the anti-reverse-installation composite tool holder for grass trimmers provided by the present invention is as follows: two bosses are arranged on the grass trimmer tool holder 5, and two bosses are also arranged on the blade 4. In this way, once the blade is reversed during the assembly process, the two bosses on the blade holder 5 cannot be placed in the corresponding grooves on the blade 4, so that they cannot be clamped and the installation can be completed. Prevent the blade from being reversed. ...

Abstract

The invention discloses a reverse-assembling-prevention composite tool apron used for a lawn pruning trolley. The reverse-assembling-prevention composite tool apron comprises a blade and a tool apron body, the tool apron body comprises a pedestal and a mounting base being perpendicular to the pedestal, and the surface, of the pedestal, being attached to the blade is provided with several bosses; the blade is fixedly arranged under the tool apron body, and the position, of the blade, being attached to the pedestal of the tool apron body is provided with several grooves corresponding to the bosses. During the mounting process, once the blade is placed reversely, the bosses on the tool apron body and the grooves in the blade cannot be buckled to complete the assembly, and the effect that the blade is prevented from being assembled reversely is effectively achieved. Especially when the several bosses are in central symmetry, the blade is prevented from being assembled reversely, the mounting angle is fixed, the weight can be further balanced, and the high-speed rotation stability can be improved. The whole reverse-assembling-prevention composite tool apron used for the lawn pruning trolley is simple in structure, high in reliability and convenient to maintain, and is stable and practical.

Description

technical field [0001] The invention relates to a grass trimming vehicle, in particular to a grass trimming vehicle cutter seat. Background technique [0002] At present, the traditional method of installing the blade of the grass trimmer is to punch two circular bosses on the blade seat, and then install the blade by matching them with the corresponding perforations and locking bolts on the blade and other related accessories. [0003] However, in this technical solution, the front or back side of the blade can be installed on the blade holder by perforating corresponding bosses, which may lead to the problem that the blade of the lawn mower is reversely mounted on the blade holder. Reverse installation not only makes it difficult to meet the work requirements of the lawn mower, but also poses a serious safety hazard, which is time-consuming and labor-intensive. SUMMARY OF THE INVENTION [0004] Purpose of the invention: In order to overcome the deficiencies in the prior...
