DETAILED DESCRIPTION

[0015] 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.

[0016] like Figure 1 to Figure 2 As shown, the present split die type adjustable tap wrench comprises a wrench housing 100, a split die 200 and a wrench handle 300. The wrench housing 100 comprises a die sleeve 110 in the middle and handle sleeves 120 at both ends. One end of the wrench handle 300 is fixedly connected to the handle sleeve 120 by a threaded connection, and a section of concave-convex pattern 310 is provided on the other end in a circumferential direction to increase the friction of the hand grip during tapping. The split die 200 is installed in the die sleeve 110, and the die sleeve 110 is provided with threaded screw holes 111 on both sides perpendicular to the axial direction of the handle sleeve 120, and locking screws 130 are installed in the screw holes 111. The split die 200 and the tap in the center thereof are fastened and fixed by rotating the locking screws 130 on both sides.

[0017] like Figure 2As shown, a circle of mounting bottom ring 113 is formed inwardly at the bottom of the die sleeve 110 to limit and receive the split die 200 mounted thereon. The split die 200 is symmetrically assembled from two half dies 210 and is mounted from top to bottom in the die sleeve 110. A plum blossom hole 230 is commonly opened in the center between the two half dies 210. The plum blossom hole 230 is provided with a die thread 211 on the inner side wall protruding inwardly, and the die thread 211 matches the tap thread at the end of the tap.

[0018] The diameter of the split die 200 should be smaller than the diameter of the inner ring of the die sleeve 110. Therefore, when the half die 210 is installed in the die sleeve 110, the two are separated from each other to form a die gap 220. Taps of different specifications within a certain range can be placed at the die thread 211 in the center of the plum blossom hole 230 for fit and fixation by adjusting the size of the die gap 220.

[0019] A vertical screw groove 212 is provided on the half die 210 on one side perpendicular to the direction of the die gap 220. When the half die 210 is installed in the die sleeve 110, the screw groove 212 is coaxial with the screw hole 111, and the locking screw 130 passes through the screw hole 111 and corresponds to the screw groove 212. The position of the half die 210 in the die sleeve 110 is adjusted by rotating the locking screw 130, so that taps of different specifications in the center can be fixed.

[0020] The die sleeve 110 has a limit strip 112 formed on the inner side wall between the screw hole 111 and the handle sleeve 120, and the number of limit strips 112 is 4. A limit groove 213 is formed on the arc-shaped outer side wall of the half die 210, and the two half dies 210 have a total of 4 sections of limit grooves 213. When the half die 210 is installed, the limit groove 213 and the limit strip 112 correspond to each other to prevent the half die 210 from running off when the relative position of the half die 210 is adjusted by the locking screw 130, so as not to affect the balance state of the tap after it is fixed.

[0021] 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.

[0022] 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.
