Specific implementation mode
For ease of understanding with implementation the utility model, the preferred embodiment combination attached drawing work of anthology utility model is furtherly
It is bright.
As shown in Figure 1, the utility model includes supporting rack and operating mechanism；
Supporting rack includes fixed link 3, and 3 outer wall bottom of fixed link is equipped with hinged at least three struts 4, adjacent two pieces strut
By being flexibly connected object connection between 4, the outer wall of every strut 4 is connect by spring 5 with 3 outer wall of fixed link；Every strut 4
Top be equipped with draw ring 8,
Operating mechanism includes operating lever 1, sleeve 2, and operating lever 1 is sheathed in sleeve 2, and 1 bottom of operating lever is hinged with pull rod
6, pull rod 6 is equipped with crotch 7 along 1 circumferencial direction arranged for interval of operating lever, the every end of pull rod 6 far from hinge joint one end；
Pull rod 6 and strut 4 are corresponding one by one, and supporting rack is hung on by draw ring 8 on the crotch 7 of pull rod 6.
As shown in Fig. 2, when implementing, supporting rack is hung on by draw ring 8 on the crotch 7 of pull rod 6, lifts operating lever 1 upwards
When, pull rod 6 turns to the inside due to by the constraint of 2 bottom face of sleeve, and then compressed spring 5, until supporting rack specification compares blasthole
12 it is smaller when, by sleeve 2 by supporting rack be sent into blasthole 12 in design position, then downwards release operating lever 1, spring 5 reset,
Strut 4 is stuck in 12 inner wall of blasthole by moment, is then slightly moved operating mechanism down once, the crotch 7 on pull rod 6 is in gravity
Effect is lower to be separated from draw ring 8, and explosive or stemming are loaded on supporting rack top；It repeats the above process, completes powder charge, primacord can
It is set between flexible connection beyond the region of objective existence end and 12 inner wall of blasthole.To improve strut 4 intensity, supporting rack card are abutted with 12 inner wall of blasthole
When in blasthole 12, spring 5 is preferably arranged to still keep compressive state.The utility model is of low cost, easy to operate, can be improved
Loading rate reduces blasting cost.
Preferably, 2 bottom of sleeve is fixedly installed collet 9, and the hole passed through for pull rod 6 is provided on collet 9.Using the reality
When applying mode, restraining force is applied to pull rod 6 by the hole on collet 9, while fixed link 3 can be connected to 9 bottom of collet, such one
Aspect can play the role of positioning to supporting rack, while can preferably ensure that supporting rack balances.
Preferably, 2 top side wall of sleeve is provided with switch hole, and switch hole is equipped with card bead 10, and card bead 10 passes through the second bullet
Spring is connect with operating lever 1, and card bead 10 is equipped by compressing switch 11.When card bead 10 is in the original state for being fastened on switch hole,
Spring 5 is in compressive state, and makes supporting rack specification more smaller than blasthole 12.When using the embodiment, by the utility model
After preparing, you can supporting rack is directly sent into design position in blasthole 12 by sleeve 2, is then pressed by compressing switch 11, just
Supporting rack can be transferred so that spring 5 resets, and strut 4 is stuck in 12 inner wall of blasthole by moment.It can be more convenient to operate using which.
In addition, also combination application can be arranged with above-mentioned collet 9 in 10 structure of card bead, when card bead 10 is in the initial shape for being fastened on switch hole
When state, fixed link 3 is connected to 9 bottom of collet.
Supporting rack installation site can be controlled rule of thumb, and the mode of simple marking can also be used, it is preferable that 2 appearance of sleeve
