fig. 1 isbase:Sub>A perspective view ofbase:Sub>A clamping and fixing mechanism, in whichbase:Sub>A handle 2 is illustrated asbase:Sub>A cylinder, and the cylinder may be in various shapes such asbase:Sub>A handle, and the inside ofbase:Sub>A sleeve 1 may be in various shapes such asbase:Sub>A square, and fig. 2 isbase:Sub>A top view of fig. 1, fig. 3 isbase:Sub>A sectional view taken alongbase:Sub>A directionbase:Sub>A-base:Sub>A in fig. 2, fig. 4 isbase:Sub>A side view ofbase:Sub>A part ofbase:Sub>A workpiece 3, fig. 5 isbase:Sub>A sectional view taken alongbase:Sub>A direction B-B in fig. 4, and fig. 6 isbase:Sub>A schematic view of the sleeve 1,base:Sub>A primary clamping assembly 4 andbase:Sub>A secondary clamping assembly 5.

As shown in fig. 1, a secondary clamping and fixing mechanism comprises a sleeve 1 for accommodating an end of a handle 2, wherein the handle 2 is provided with a primary hole 201 and a secondary hole 202 (shown in fig. 3); the utility model discloses set up sleeve 1, can hold the tip of handle 2, wherein, handle 2 can be the check rod, for example the check rod of PH value detector, the check rod of conductivity detector, the tip of the straw of liquid in the absorption cauldron etc. because often appear in the factory check rod or straw etc. and place often by the people mistake when the cauldron next door and bump, perhaps bumped by the mistake of kettle cover, manipulator, detection apparatus etc. and the phenomenon that drops appears check rod, straw etc., consequently, the utility model discloses utilize sleeve 1 to hold it, recycle subsequent a centre gripping subassembly 4 and secondary centre gripping subassembly 5 and carry out twice centre gripping, guarantee to be bumped the back by the mistake and also can not drop. Only need set up two apertures, once hole 201 and secondary hole 202 in the outer wall at test rod or straw tip, the size in two holes need not too big, need not too deep, during the in-service use, and the trompil can all be realized to the tip of pH value detector, conductivity detector, straw etc.. The working piece 3 arranged on the handle 2 is a detection rod, a suction pipe and the like which are only shown in the figure.

As shown in fig. 1, the side wall of the sleeve 1 is provided with a primary clamping assembly 4 and a secondary clamping assembly 5, the inner bottom is provided with an ejecting member 6 (shown in fig. 3) for ejecting the handle 2, and in conjunction with fig. 3, the primary clamping assembly 4 comprises a primary clamping rod 401, and the secondary clamping assembly 5 comprises a secondary clamping rod 501 and an elastic reset unit connected to the secondary clamping rod 501; the primary clamping rod 401 can extend into the primary hole 201, and the secondary clamping rod 501 extends into the secondary hole 202 under the action of the elastic reset unit. After primary holding rod 401 stretched into primary hole 201, direct restriction handle 2's motion, leave primary hole 201 back when primary holding rod 401, secondary holding rod 501 still stretches into in the secondary hole 202 and guarantees that handle 2 can not oneself leave sleeve 1, unless elasticity reset unit takes secondary holding rod 501 to also leave secondary hole 202, handle 2 can break away from sleeve 1, utilize twice to loosen, could take off handle 2, guarantee even by the mistake bump, even once holding rod 401 is pulled open by carelessness, handle 2 also has secondary holding rod 501 to centre gripping.

The primary clamping assembly 4 further comprises a first limiting plate 402 arranged at the inner end of the primary clamping rod 401, and the secondary clamping assembly 5 further comprises a second limiting plate 502 arranged at the inner end of the secondary clamping rod 501; the first restriction plate 402 can extend into the primary bore 201 and the second restriction plate 502 can extend into the secondary bore 202. The first limiting plate 402 and the second limiting plate 502 are used for preventing the primary clamping rod 401 and the secondary clamping rod 501 from separating from the sleeve 2, and specifically, with reference to fig. 5, the sidewall of the sleeve 1 is provided with a first hole 104 for penetrating the primary clamping rod 401 and a second hole 105 for penetrating the secondary clamping rod 501; the inner end of the first hole 104 is provided with a first limiting groove 101 for accommodating the first limiting plate 402, and the inner end of the second hole 105 is provided with a second limiting groove 102 for accommodating the second limiting plate 502. After the primary clamping rod 401 and the secondary clamping rod 501 are pulled out, the first limiting plate 402 and the second limiting plate 502 enter the first limiting groove 101 and the second limiting groove 102 respectively, so that the handle 2 can be led to the outside smoothly, and the primary clamping rod 401 and the secondary clamping rod 501 can not be lost.

Referring to fig. 6, the elastic reset unit includes a guide rod 503, a guide limit plate 504, and a clamping spring 505, the outer wall of the sleeve 1 is provided with the mounting frame 103, one end of the guide rod 503 is fixed to the secondary clamping rod 501, the other end of the guide rod is fixed to the guide limit plate 504 after penetrating through the mounting frame 103, and the clamping spring 505 is sleeved in the guide rod 503 and located between the mounting frame 103 and the secondary clamping rod 501. Pulling direction limiting plate 504, alright in order to realize secondary supporting rod 501's action for secondary supporting rod 501 has the trend to handle 2 motion all the time under the spring action, guarantees that secondary supporting rod 501 only can leave handle 2 under the exogenic action, guarantees that handle 2 can not break away from by oneself.

Referring to fig. 3, the length of the secondary hole 202 is greater than that of the primary hole 201, so that the secondary clamping bars 501 are respectively located at both ends of the secondary hole 202 when the primary clamping bar 401 is inserted into and pulled out of the primary hole 201. As shown in fig. 3, the secondary apertures 202 and the primary apertures 201 are aligned at one end and differ in length at the other end.

Combine fig. 3, cooperation pop-up 6, pop-up 6 adopts and pops out the spring, be a supporting rod 401 in fig. 3, the equal centre gripping handle's of secondary supporting rod 501 schematic diagram, when a supporting rod 401 is taken out, handle 2 is under the effect of below pop-up 6, and under the space effect of secondary hole 202, handle 2 outwards movement, until moving the lateral wall that arrives secondary hole 202 and being blocked no longer the motion by secondary hole 202, at this moment, pull open direction limiting plate 504 and make secondary supporting rod 501 take out, handle 2 outwards moves until being popped out under the effect of popping out 6, take off handle 3 can.

During the installation, all pull out primary clamping rod 401, secondary clamping rod 501, place handle 2 in sleeve 1, make secondary hole 202 and primary hole 201 align primary clamping rod 401, secondary clamping rod 501 and be held.

During the use, can place whole device level (wholly fall in fig. 1), once supporting rod 401 is above promptly, and secondary supporting rod 501 is in the below, and the opening of sleeve 1 is towards the side, and secondary supporting rod 501 still utilizes elasticity to guarantee the centre gripping in the below, and the primary supporting rod 401 of top utilizes the dead weight to fall downtheholely to one time.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any form, and all the changes and modifications equivalent to any simple modification made by the technical entity of the present invention to the above embodiments are within the scope of the technical solution of the present invention.
