Abstract
The invention relates to a fisher drilling tool head part installation structure. The fisher drilling tool head part installation structure comprises a fishing spear seat and a fishing spear head, wherein the upper part of the fishing spear seat is provided with a boss; the top of the boss is provided with an inward concave structure; a connecting plate at the bottom of the fishing spear head is connected with the boss of the fishing spear seat through a fastening element; a first groove is formed in the middle part of the fishing spear head; the lower part of the first groove is provided with a positioning pressing block; a second groove is formed in the upper part of the positioning pressing block, and is internally provided with a spring; the other end of the spring extends to the top of the first groove; the lower part of the positioning pressing block is provided with a protruding structure which is fit with and butts against the inward concave structure arranged on the boss. The fisher drilling tool head part installation structure provided by the invention is reasonable and compact, and is convenient to install; a fisher can clamp the fishing spear head easily, convenience is brought to the fishing operation, and the working efficiency is high.
Description
Technical field
The present invention relates to fisher technical field, especially a kind of fisher drilling tool head mounting structure.
Background technology
Fisher is the novel bit hook that the metal that sinks was salvaged or found to modern specialty, for maritime affairs salvaging, public security, special policeman, fire-fighting, and Archaeological Exploration, the departments such as industry cleaning under water, search and salvage victim, material evidence, shipwreck etc. in water.
Fisher when work, fisher need to be blocked and drags for spearhead, in prior art, drag for spearhead and adopt one-piece construction, when real work, one-piece construction drag for the more difficult fisher that blocks of spearhead, or easily produce the phenomenon coming off, to fishing job, brought trouble.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of fisher drilling tool head mounting structure rational in infrastructure, thereby can by dragging for spearhead, be stuck on fisher easily, facilitates fishing job, increases work efficiency.
The technical solution adopted in the present invention is as follows:
A drilling tool head mounting structure, comprises and drags for lance seat, described in drag for lance seat top and be provided with boss, the top of described boss is provided with concave inward structure; Also comprise and drag for spearhead, the described connecting panel that drags for spearhead bottom is connected with the boss that drags for lance seat by fastener, the described spearhead middle part of dragging for has the first groove, described the first groove bottom is provided with location briquetting, the top of described location briquetting has the second groove, in described the second groove, spring is installed, the other end of described spring extends to the top of the first groove; The bottom of described location briquetting is provided with projective structure, and described projective structure coordinates butt with concave inward structure set on boss.
Further improvement as technique scheme:
The described connecting panel that drags for spearhead bottom is fixed by elastic cylindrical pin and the boss that drags for lance seat;
The described lance seat bottom of dragging for has slotted hole.
Beneficial effect of the present invention is as follows:
The present invention is reasonable, compact, easy for installation, and fisher can be easy to block and drag for spearhead, to fishing job, has brought convenience, and work efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is front view of the present invention (full sectional view).
Wherein: 1, drag for spearhead; 2, boss; 3, elastic cylindrical pin; 4, slotted hole; 5, drag for lance seat; 6, the first groove; 7, spring; 8, the second groove; 9, location briquetting.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, the fisher drilling tool head mounting structure of the present embodiment, comprises and drags for lance seat 5, drags for lance seat 5 tops and is provided with boss 2, and the top of boss 2 is provided with concave inward structure; Also comprise and drag for spearhead 1, the connecting panel that drags for spearhead 1 bottom is connected with the boss 2 that drags for lance seat 5 by fastener, drag for spearhead 1 middle part and have the first groove 6, the first groove 6 bottoms are provided with location briquetting 9, the top of location briquetting 9 has the second groove 8, in the second groove 8, spring 7 is installed, the other end of spring 7 extends to the top of the first groove 6; The bottom of location briquetting 9 is provided with projective structure, and projective structure coordinates butt with concave inward structure set on boss 2.
The connecting panel that drags for spearhead 1 bottom is fixing with the boss 2 that drags for lance seat 5 by elastic cylindrical pin 3.
Drag for lance seat 5 bottoms and have slotted hole 4.
In actual use procedure, when salvaging, fisher can be easy to block and drag for spearhead 1.Due to the compression function of spring 7, location briquetting 9 can in the vertical direction up-and-down movement, thereby make to drag for spearhead 1, can realize and swinging, under actual conditions fisher and drag for spearhead 1 center can not be in full accord.So can swing regulate in the situation that dragging for spearhead 1, for fisher, block and drag for spearhead 1 and be just very easy to.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
