Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic electric tool accessories, in particular to a handheld grip connection plate for a pneumatic electric tool. Background Art

[0002] Pneumatic tools are a general term for tools powered by compressed air. Compressed air causes pistons and other parts to produce different movements to work. Pneumatic picks, pneumatic rock drills, and pneumatic riveters are some of the tools that perform linear reciprocating motion and produce impact force. At present, most pneumatic tools use connecting plates to fix the hand grip to the pneumatic power tool. However, after the hand grip is fixed to the connecting plate, the inclination angle of the hand grip cannot be changed, which makes it impossible for the user to adjust the angle between the hand grip and the pneumatic power tool according to different usage requirements, making it impossible for the user to hold the hand grip in a comfortable posture. At the same time, the vibration generated by the pneumatic power tool during operation will be directly transmitted to the hand grip, which often causes the user to feel a strong vibration when holding the hand grip, resulting in a low comfort level when holding the hand grip. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art, such as: at present, after the hand-held handle is fixed on the connecting plate, the inclination angle of the hand-held handle cannot be changed, which makes it impossible for the user to adjust the angle between the hand-held handle and the pneumatic power tool according to different usage requirements, thereby making it impossible for the user to hold the hand-held handle in a comfortable posture. At the same time, since the vibration generated by the pneumatic power tool during operation will be directly transmitted to the hand-held handle, when the user holds the hand-held handle, the vibration of the hand-held handle is often strong, resulting in a low comfort level for the user when holding the hand-held handle. Therefore, a hand-held handle connecting plate for a pneumatic power tool is proposed.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, a third connecting block is fixedly connected to the upper surface of the first mounting plate, a hollow sphere is fixedly connected to the upper surface of the third connecting block, a second circular hole is opened on the side of the hollow sphere, and a shock-absorbing bracket is fitted on the inner wall of the hollow sphere.

[0008] Preferably, the shock absorbing bracket includes a third mounting plate, a fourth connecting block is fixedly connected to the bottom of the third mounting plate, spring shock absorbers are fixedly connected to the left and right sides of the fourth connecting block, one end of the spring shock absorber is fixedly connected to the fifth connecting block, a second cylinder is fixedly connected to the side of the fifth connecting block, a solid sphere is fixedly connected to one end of the second cylinder, the surface of the solid sphere is in contact with the inner wall of the hollow sphere, a U-shaped column is fitted on the surface of the fifth connecting block, and the upper surface of the U-shaped column is fixedly connected to the bottom of the third mounting plate.

[0009] Preferably, the diameter of the solid sphere is smaller than the inner diameter of the hollow sphere, the diameter of the solid sphere is larger than the diameter of the second circular hole, and the diameter of the second circular hole is larger than the diameter of the second cylinder.

[0010] Preferably, the right side of the rack is fixedly connected to a limiting block.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The utility model enables the rack to be adjusted and locked by cooperating with the second connecting block, the threaded hole, the positioning bolt and the positioning groove. At the same time, when the position of the rack is changed, the angle between the second mounting plate and the cover plate can be changed by cooperating with the rotating bracket, the rack and the gear. After the hand-held handle is fixed to the pneumatic power tool through the connecting plate, the angle between the hand-held handle and the pneumatic power tool can be adjusted as needed through the connecting plate.

[0013] (2) The utility model uses the coordination of the hollow sphere and the solid sphere to enable the spring shock absorber on the shock absorber bracket to deform when the shock absorber bracket moves in any direction, and the deformed spring shock absorber can reduce the vibration transmitted from the pneumatic power tool to the hand-held handle, thereby effectively reducing the vibration of the hand-held handle of the pneumatic power tool when it is working, thereby improving the comfort of the user when holding the hand-held handle.
