In the figure, 1 part of a ruler needle, 1-1 part of an eccentric step, 2 parts of a ruler body, 2-1 parts of a plane A, 2-2 parts of a plane B, 2-3 parts of a locking groove, 3 parts of a sleeve, 4 parts of a locking structure, 5 parts of a handle.

Detailed Description

Fig. 1 to 7 are schematic side structural views of the present invention, and a novel depth finder is characterized by comprising a ruler needle 1, a ruler body 2, a sleeve 3 and a locking structure 4; the ruler needle 1 is inserted into the ruler body 2 to form an integral structure; the ruler body 2 is detachably inserted into the sleeve 3 and locked and limited through the locking structure 4, the ruler needle 1 extends out from one end of the sleeve 3, the ruler body 2 extends out from the other end of the sleeve 3, and scale marks for displaying hole depth are marked on the ruler body 2; the locking structure 4 is fixed on the sleeve 3.

The specific principle is as follows: in the application, the ruler needle 1 is inserted into the ruler body 2 to form a stable integral structure, the sleeve 3 is used for covering, the locking structure 4 is limited and fixed, the sleeve 3 can slow down abrasion in the operation process, and the locking structure 4 cannot fall off to cause operation risks; after the measurement is completed, the blade 2 can be removed from the sleeve 3, thereby facilitating cleaning. The structure of this application, the corrosion that can avoid the product and because the piece problem that wearing and tearing appear can guarantee to measure accurately, can take out blade 2 again, convenient washing.

According to another embodiment of the utility model, the end part of the ruler needle 1 is provided with an eccentric step 1-1 which can effectively hook the outer side wall of the bottom of the inner hole, so as to provide a positioning surface and further ensure the measurement accuracy.

According to another embodiment of the present invention, it is further included that the material of the sleeve 3 is plastic, and by using the material characteristics of the plastic, the problems of corrosion and debris due to abrasion of the product are further avoided.

According to another embodiment of the utility model, the locking structure 4 is a positioning pin, the front end of the ruler body 2 is provided with two groups of planes A2-1 and B2-2 which are staggered by 180 degrees, the right side of the plane B2-2 is provided with a locking groove 2-3, and the positioning pin is clamped at the locking groove 2-3.

In the specific working process, after the ruler needle 1 is inserted into the ruler body 2 to form an integral structure, one end of the ruler needle 1 is firstly inserted into the inner hole of the sleeve 3, meanwhile, the plane A2-1 of the ruler body 2 is ensured to be positioned at one side of the positioning pin, and the plane A2-1 is parallel to the axis of the positioning pin, so that the positioning pin can be continuously inserted forwards through the plane A2-1, when the positioning pin is positioned between the plane A2-1 and the plane B2-2, the ruler body 2 rotates 180 degrees, so that the plane B2-2 is positioned at one side of the positioning pin, and plane B2-2 is parallel to the axis of the locating pin, so that the locating pin can pass through plane B2-2, therefore, the positioning pin is continuously inserted to enable the positioning pin to pass through the plane B2-2 until the positioning pin is positioned in the locking groove 2-3, the ruler body 2 is rotated by 180 degrees, the positioning pin is contacted with the locking groove 2-3, and the ruler body 2 can be limited from falling out. Finally, the head of the ruler needle 1 is inserted into the inner hole to be measured, and the scale is read on the ruler body 2 at the moment, so that the depth of the hole to be measured is known.

According to another embodiment of the utility model, the positioning pin is assembled on the side wall of the sleeve 3 in an interference fit mode, the interference fit mode can limit the ruler body 2 from falling out, and in addition, the positioning pin is not easy to fall off.
