The loss situation adjustment of the body through-hole A fixed with lifting device, increases the access times of boom main body, reduces failure rate, promoted
Production efficiency, however, the technology has the disadvantage that after loss has occurred, in order to allow fixture preferably and after replacement
Through-hole is fixed, and is required to that serious clamp segment or the corresponding position excision of linkage section, heavy workload will be lost；Also, it cuts every time
Except the length for all shortening entire boom, whole is finally needed to scrap, to accelerate the speed that whole boom is scrapped.In view of existing
There is defect existing for technology, it would be highly desirable to a method of it is able to solve above-mentioned technological deficiency.
Utility model content
Based on this, the purpose of this utility model is to provide a kind of modified form pcb boards to spray tin boom, is hung by redesigning
On the one hand the structure of arm facilitates and on the other hand scraps boom without whole for the excision that section is lost when being lost, thus
Reduce cost.
The utility model provides a kind of modified form pcb board spray tin boom, including suspension plate body, and the suspension plate body is along its length
One end array in degree direction is provided with several suspension through-holes, and the other end of the suspension plate body along its length is convexly equipped with U-shaped
Slot is embedded with connecting rod in the U-type groove, and one end of the connecting rod is fixed with the U-type groove by rivet, the connecting rod
The other end extend to outside the U-type groove；The connecting rod is made of several with the matched link block of fixture, each link block
Between connected by linkage section, each link block is provided with through-hole A；Array is arranged the U-type groove along its length
There are several through-hole Bs corresponding with the link block through-hole A；The area of each linkage section and the contact surface of the link block is equal
Less than the area in the face that link block is connect with linkage section.
As preferred mode, the quantity of the suspension through-hole is set as N, N > 1.
As preferred mode, the quantity of the link block is set as M, M > 8.
As preferred mode, when initial use state, the entire length of the connecting rod is greater than the entirety of the U-type groove
Length.
As preferred mode, the quantity of the through-hole B is set as S, S > 1.
The utility model has the following beneficial effects: connecting rod is made of several with the matched link block of fixture, each link block it
Between connected by linkage section, if the loss of one section of link block is big, directly disconnected from linkage section present position, allow fixture with next section
Link block fixed by rivet, then proceed to using, due to the area of each linkage section and the contact surface of link block be respectively less than connect
The area in the face that block is connect with linkage section is connect, therefore, convenient for extracing；Connecting rod, one end of connecting rod and U are embedded in U-type groove
Type groove is fixed by rivet, if connecting rod has been lost, can directly replace connecting rod, is retained suspension plate body, is not necessarily to whole
Boom is scrapped, to reduce cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Appended drawing reference are as follows: suspension plate body 10, suspension through-hole 11, rivet 12, connecting rod 13, fixture 14, through-hole A15, connection
Block 16, linkage section 17, through-hole B18, U-type groove 19.
Specific embodiment
For the feature, technological means and specific purposes achieved, function that can further appreciate that the utility model, below
The utility model is described in further detail in conjunction with specific embodiment and attached drawing.
As shown in Figure 1, the utility model provides a kind of modified form pcb board spray tin boom, including suspension plate body 10, it is described outstanding
One end array of hanging plate body 10 along its length is provided with several suspension through-holes 11, and the suspension plate body 10 is along its length
The other end be convexly equipped with U-type groove 19, be embedded with connecting rod 13 in the U-type groove 19, one end of the connecting rod 13 with it is described U-shaped
Slot 19 is fixed by rivet 12, and the other end of the connecting rod 13 extends to outside the U-type groove 19；The connecting rod 13 is by several
