The utility model utilizes spring chuck and folder post to be coupled together, when mounting terminal because spring is in compressive state, chuck top is pushed up to chuck place, chuck is in gathers state, external force is needed to be pulled by chuck downwards, now spring is further compressed, chuck top is away from chuck place, now chuck is expansion state, is now inserted in folder hole terminal one end, then unclamps chuck, chuck makes chuck top be back to chuck place under the effect of spring power, and then chuck is gathered, thus terminal clamp is held in chuck, can pull-out test be carried out.
Further, for avoiding terminal slippage from folder hole in test process, described folder hole inwall is rough surface.
As preferably, above-mentioned rough surface is that folder hole inwall is distributed with salient point.
As preferably, described folder post top is the chuck be made up of two semicircle column type Elastic clamping plates.
As preferably, described fixed leg is notch cuttype, is less than spring diameter near chuck one end diameter, spring diameter is greater than away from chuck one end diameter, only need be connected on fixed leg by spring housing, the bottom of spring is resisted against on fixed leg notch cuttype transition face, facilitates the installation of spring.
As preferably, described jackets inner wall is notch cuttype, and its upper inner diameter is equal with chuck external diameter, lower inner diameter is greater than spring diameter, when being socketed in by chuck on folder post, spring top is directly resisted against on jackets inner wall notch cuttype transition face, the aspect assembling of device.The two ends of spring can certainly be separately fixed on the outer wall of fixed leg and the inwall of chuck, equally also well can be applicable to the utility model.
Further, described pedestal is stepped right cylinder, and its upper end diameter is greater than lower end diameter, and described instrument connection is opened in the less one end of diameter; Described support has the mounting hole for mounting body, described mounting hole diameter is not less than the diameter of the less one end of pedestal diameter, is less than the diameter of the larger one end of diameter.During installation, the less one end of pedestal diameter is passed down through mounting hole, and the larger one end of diameter is stuck on mounting hole, and in pull-out test process, pedestal can not from slippage in mounting hole
As preferably, described propulsion system are cylinder, and described folder post is fixedly mounted on cylinder output terminal.
The beneficial effects of the utility model are, the utility model structure is simple, are especially easy to operation, can be clamped by terminal simply and effectively.

Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Embodiment 1
As shown in figs. 1 and 3, a kind of simple terminal pull-out test instrument, comprises support 1, is arranged on support 1 and provides the propulsion system of pulling force for the pedestal 2 of calibrating terminal drawing property with for the clamp device that clamps terminal 7 with for test; Described pedestal 2 has the instrument connection for mounting terminal 7; Described pedestal 2 is stepped right cylinder, and its upper end diameter is greater than lower end diameter, and described instrument connection is opened in the less one end of diameter; Described support 1 has the mounting hole for mounting body 2, described mounting hole diameter is not less than the diameter of the less one end of pedestal 2 diameter, is less than the diameter of the larger one end of diameter.During installation, the less one end of pedestal 2 diameter is passed down through mounting hole, and the larger one end of diameter is stuck on mounting hole, and in pull-out test process, pedestal 2 can not from slippage in mounting hole.
Described clamp device comprises folder post and chuck 5, described folder post top is the chuck 3 be made up of two semicircle column type Elastic clamping plates, bottom is the fixed leg 4 being set with spring 8, and described chuck 3 center is the folder hole 31 for mounting terminal 7, and folder hole 31 inwall is evenly distributed with salient point; Described chuck 5 is socketed on folder post, be fixed on fixed leg 4 bottom spring 8, top is fixedly mounted on chuck 5 inwall, described chuck 5 upper inner diameter equal with chuck 3 external diameter (external diameter of cylinder of described chuck 3 external diameter for being formed when two semicircle column type Elastic clamping plates are gathered).Described propulsion system are cylinder 6, and described folder post is fixedly mounted on cylinder 6 output terminal.
When mounting terminal 7 because spring 8 is in compressive state, chuck 5 top is pushed up to chuck 3 place, chuck 3 is in gathers state, external force is needed to be pulled by chuck 5 downwards, as shown in Figure 1, now spring 8 is further compressed, chuck 5 top is away from chuck 3 place, now chuck 3 is expansion state, now terminal 7 one end is inserted in folder hole 31, then chuck 5 is unclamped, as shown in Figure 3, chuck 5 makes chuck 5 top be back to chuck place under spring 8 resilient force, and then chuck 3 is gathered, thus terminal 7 is clamped in chuck 3, pull-out test can be carried out.
