[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a kind of tool for removing cover, including handle, dismounting head;Handle is installed at one end of dismounting head, the outer diameter of dismounting head is less than the inner diameter of fastener mounting hole on cover, and through hole is set up in the end of dismounting head away from handle, and clamping block structure is installed in through hole, and clamping block structure enters or extends into through hole under the influence of extrusion force of fastener mounting hole.

[0005] Preferably, clamping block structure includes special-shaped clamping block, spring;The number of special-shaped clamping block is two, and is installed at the two ends of spring respectively;Spring is located in through hole, and special-shaped clamping block enters or extends into through hole under the influence of extrusion force of fastener mounting hole.

[0006] Preferably, the end of special-shaped clamping block away from spring includes arc surface and clamping surface, arc surface is connected with clamping surface, and clamping surface is matched with the inner surface of cover.

[0007] Preferably, special-shaped clamping block is made of copper material, and its hardness is lower than the hardness of cover, so that product is not easy to be damaged when dismounting cover.

[0008] Preferably, special-shaped clamping block, spring and dismounting head are combined integral structure, have multiple specifications, and can be used in fastener mounting hole on cover with different inner diameters, and have high adaptability.

[0009] Preferably, the outer diameter of handle is greater than the outer diameter of dismounting head.

[0010] Preferably, the outer surface of handle is provided with lace texture, which plays the role of antiskid.

[0011] Compared with prior art, the utility model has the following advantages:

[0012] 1. effectively improve the ability to disassemble the cover, speed up the assembly efficiency;

[0013] 2. can adapt to various types and sizes of cover, wide application range;

[0014] 3. reduce the cover disassembly process caused by severe damage to scrap, thereby reducing production costs. BRIEF DESCRIPTION OF DRAWINGS

[0015] Figure 1 is a structural schematic diagram of an embodiment of the present application;

[0016] 1-removable handle; 2-rod dismounting head; 3-irregular shaped block; 4-spring; 5-housing; 6-cover; 7-rubber pad. DETAILED DESCRIPTION

[0017] The following will be combined with the drawings Figure 1 Further details of the present application: a tool for disassembling the cover, comprising a removable handle 1, a connecting rod dismounting head 2, an irregular shaped block 3 and a spring 4; The removable handle 1 is installed at one end of the connecting rod dismounting head 2, the outer diameter of the connecting rod dismounting head 2 is smaller than the inner diameter of the fastener mounting hole on the cover 6, a through hole is radially provided at the end of the connecting rod dismounting head 2 away from the removable handle 1, the through hole penetrates the connecting rod dismounting head 2 radially, the block structure is installed in the through hole, under the influence of the extrusion force of the fastener mounting hole, the block structure enters or extends out of the through hole, in this embodiment, the block structure includes an irregular shaped block 3 and a spring 4, the number of irregular shaped blocks 3 is two, which are installed at both ends of the spring 4.

[0018] In order to facilitate the connecting rod dismounting head 2 to enter the fastener mounting hole, the end face of the irregular shaped block 3 entering the fastener mounting hole is provided as an arc surface; In order to facilitate the cover 6 to be disassembled from the housing 5 and separated from the rubber pad 7, the end face matched with the arc surface matches the inner surface of the cover 6.
