Description

Technical Field

[0001] This utility model relates to a ratchet wrench combination tool. It belongs to the technical field of ratchet wrenches. Background Technology

[0002] A ratchet wrench is a manual screw tightening and loosening tool that allows users to easily tighten or loosen bolts or nuts. However, most conventional ratchet wrenches use a single retaining ring to hold the ratchet in place. This makes the wrench prone to slippage and dislodgement after prolonged use, increasing the difficulty of machining and installation for both operators and installers. Furthermore, the lack of effective protection for the locking mechanism and teeth allows foreign objects to easily enter between the ratchet and teeth, increasing wear on the locking or external teeth and affecting the wrench's lifespan. Utility Model Content

[0003] This utility model proposes a ratchet wrench combination tool that expands the versatility of the ratchet wrench and its extension rod during use by setting two retaining rings and two pressure holes, and avoids the problem of the ratchet wrench falling off, thus solving the problems existing in the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A ratchet wrench combination tool includes a ratchet wrench and an extension rod used in conjunction with the ratchet wrench; the ratchet wrench includes a wrench main rod and a ratchet seat, a ratchet is embedded in the ratchet seat, a C-shaped retaining ring is inserted into a groove on one side of the ratchet, and a gate-shaped retaining ring is inserted into a groove on the opposite side; the gate-shaped retaining ring and the C-shaped retaining ring can provide double restraint for the extension rod, making it less likely to fall off.

[0006] The connecting rod includes a hexagonal rod and a round rod from left to right. The hexagonal rod has a first pressing hole and a second pressing hole for limiting the gate-type retaining ring and the C-type retaining ring.

[0007] The ratchet seat is equipped with a knob for adjusting the clockwise or counterclockwise rotation of the ratchet.

[0008] The first and second pressure holes are distributed intermittently on the hexagonal rod.

[0009] One end of the round rod has an internal hexagonal hole for the connecting rod. The connecting rod can also be used separately for manual tightening and loosening of the screws.

[0010] The outer contour dimension of the hexagonal rod is smaller than that of the round rod.

[0011] The ratchet has a hexagonal hole on one side and a dodecagonal hole on the opposite side. Specifically, a C-shaped retaining ring is inserted into a slot on the hexagonal hole side, and a portal retaining ring is inserted into a slot on the dodecagonal hole side.

[0012] The main wrench has an internal hexagonal hole at one end. The main wrench can also be used alone for manually tightening or loosening screws.

[0013] This utility model has the following advantages and beneficial effects:

[0014] This utility model relates to a ratchet wrench combination tool with two retaining rings and two pressure holes to expand the versatility of the ratchet wrench and extension rod during use. When the second pressure hole is engaged with the two retaining rings, the user can manually tighten or loosen the bolt in an L-shape. When the first pressure hole is engaged with the two retaining rings, the user can manually tighten or loosen the bolt in a T-shape. This makes it more convenient for users to operate under different working conditions or in confined spaces, facilitating processing by machining personnel and assembly by installation personnel.

Detailed Implementation

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Reference Figure 1-4 A ratchet wrench combination tool includes a ratchet wrench and an extension bar 9 for use with the ratchet wrench; the ratchet wrench includes a wrench main bar 1 and a ratchet seat 4, wherein a ratchet 5 is embedded in the ratchet seat 4, as shown in the figure. Figure 5 The ratchet 5 has an inner slot on one side for inserting a C-shaped retaining ring 7, and an inner slot on the opposite side for inserting a portal retaining ring 8; the portal retaining ring 8 and the C-shaped retaining ring 7 can provide double restraint for the connecting rod 9, making it less likely to fall off. The ratchet seat 4 is equipped with a knob 3 for adjusting the clockwise or counterclockwise rotation of the ratchet 5.

[0024] The ratchet 5 has a ratchet hexagonal hole 6 on one side and a ratchet dodecagonal hole 13 on the opposite side. Specifically, a C-shaped retaining ring 7 is inserted into a slot on the ratchet hexagonal hole 6 side, and a portal retaining ring 8 is inserted into a slot on the ratchet dodecagonal hole 13 side.

[0025] The main wrench 1 has an internal hexagonal hole 2 at one end. The main wrench 1 alone can also be used for manual tightening and loosening of screws.

[0026] The connecting rod 9 comprises a hexagonal rod and a round rod from left to right. The hexagonal rod has a first pressing hole 11 and a second pressing hole 12 for positioning the gate-type retaining ring 8 and the C-type retaining ring 7.
