However, the disassembling tool is used for disassembling the tunnel nut and cannot be applied to the product.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide an in put motor ratchet mounting tool, it has the advantage that improves ratchet installation effectiveness and quality.
In order to achieve the above purpose, the utility model provides a following technical scheme:
a middle motor ratchet wheel mounting tool comprises a linkage plate, wherein a ratchet part matched with a ratchet wheel is arranged on the outer circumferential side wall of the linkage plate; a clamping groove is formed in the side wall of the outer circumference of the linkage plate, and a retaining ring is embedded in the clamping groove; and a connecting rod is arranged in the middle of the linkage plate.
Furthermore, the connecting rod is detachably connected with the linkage plate.
Furthermore, a locking plate is arranged on the end face of the linkage plate, and a positioning hole matched with the connecting rod is formed in the middle of the locking plate; the outer side wall of the locking plate is provided with a threaded hole communicated with the positioning hole, and a locking bolt of which the end part is in contact with the connecting rod is screwed in the threaded hole.
Further, the cross section of the positioning hole is polygonal.
Further, the cross section of the positioning hole is hexagonal.
Further, the number of the locking bolts is at least two.
Further, the retainer ring is a circlip.
To sum up, the utility model discloses following beneficial effect has:
1. the connecting rod can be connected with a standard universal rotating tool, and can be quickly replaced, so that the production cost can be reduced;
