Description

Technical Field

[0001] The utility model belongs to the technical field of tap wrenches, and particularly relates to a ratchet tap wrench with a clamping shaft. Background Art

[0002] The ratchet tap wrench is a tapping tool that is based on the principle of force balance and can quickly transmit rotational force to achieve rapid tapping. This wrench has a wide range of uses and is suitable for taps of various specifications, especially for difficult-to-process areas, greatly improving the efficiency of tapping.

[0003] The ratchet tap wrench in the prior art usually consists of a wrench body and an insertion rod installed laterally thereon. When tapping, the user holds the insertion rod and drives the wrench body to rotate and tap. However, since the wrench body and the insertion rod are movably connected, the insertion rod is prone to lateral displacement during tapping, which may cause the user to slip during tapping or cause poor tapping quality due to uneven force. Utility Model Content

[0004] The utility model aims to solve the above problems in the prior art and to provide a ratchet tap wrench with a clamping shaft, which can relatively fix a hand-held insert rod and a wrench body when in use.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a ratchet tap wrench with a clamping shaft, comprising a wrench body, a fixed clamping shaft and a hand-held insertion rod, the top of the wrench body is provided with a clamping shaft mounting hole from top to bottom, the upper side is provided with an insertion rod mounting hole penetrating the clamping shaft mounting hole, and the inner wall of the clamping shaft mounting hole is provided with an inner thread;

[0006] A hand-held plug rod is inserted and installed in the plug rod installation hole, and a plug shaft external thread is formed on the outer side wall of the fixed card shaft. The fixed card shaft is screwed into the card shaft installation hole from top to bottom to tighten and fix the hand-held plug rod below.

[0007] In the above-mentioned ratchet tap wrench with a clamping shaft, a conical head is formed at the bottom end of the fixed clamping shaft, and a limiting groove is opened in the middle of the hand-held insertion rod. During installation, the conical head extends into the limiting groove to tighten and fix the hand-held insertion rod.

[0008] In the above-mentioned ratchet tap wrench with a clamping shaft, the number of the rod mounting holes on the wrench body is not less than 2.

[0009] In the above-mentioned ratchet tap wrench with a clamping shaft, friction lines are arranged on the outer side walls at both ends of the hand-held insert rod.

[0010] Compared with the prior art, the ratchet tap wrench with a clamping shaft provided by the utility model relatively fixes the assembled wrench body and the hand-held insert rod by fixing the clamping shaft, so that it is not easy to slip during tapping, and the tapping quality is effectively improved.

DETAILED DESCRIPTION

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 to Figure 2 As shown, the ratchet tap wrench with a clamping shaft comprises a wrench body 100, a fixed clamping shaft 200 and a hand-held insert rod 300. A clamping shaft mounting hole 110 is provided at the top of the wrench body 100 along the central axis from top to bottom, an inner hole thread 111 is provided on the inner wall of the clamping shaft mounting hole 110, and a clamping shaft outer thread 210 is formed on the outer wall of the fixed clamping shaft 200. The clamping shaft outer thread 210 cooperates with the hole inner thread 111, so that the fixed clamping shaft 200 can be screwed into the clamping shaft mounting hole 110 from top to bottom.

[0016] The upper end of the wrench body 100 is provided with a rod mounting hole 120 on the side that passes through the shaft mounting hole 110, and a hand-held rod 300 is inserted and installed in the rod mounting hole 120. The number of the rod mounting holes 120 provided on the wrench body 100 should be no less than 2, so that the user can insert the hand-held rod 300 into the rod mounting holes 120 of different heights for tapping according to actual needs.

[0017] A conical head 220 is formed at the bottom end of the fixed clamping shaft 200, and a limiting groove 310 is provided in the middle of the hand-held insert rod 300. When assembling the tap wrench, the hand-held insert rod 300 is first inserted into the insert rod mounting hole 120 of the required height, and then the fixed clamping shaft 200 is screwed into the clamping shaft mounting hole 110 until the conical head 220 of the fixed clamping shaft 200 extends into the limiting groove 310 of the hand-held insert rod 300 to tighten and fix it, so as to prevent the hand-held insert rod 300 from lateral displacement during tapping, resulting in slipping during tapping or poor tapping quality due to uneven force.

[0018] To further illustrate, friction lines 320 are provided on the outer side walls at both ends of the hand-held insertion rod 300. The friction lines 320 further enhance the friction between the user's hand and the hand-held insertion rod 300, making it easier for the user to perform tapping.

[0019] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0020] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
